Create Windows 7 Universal ISO With All Editions Selection On Install with ei.cfg Removal Utility

For Windows users who switch and upgrade from Windows Vista, one difference will be immediately noticeable when installing or upgrading to Windows 7, i.e. Install Windows 7 setup wizard no longer prompts or asks for user selection of which edition of the operating system to install. Instead, each Windows 7 DVD disc or Windows 7 ISO image will automatically install the preset specific edition which it’s confined to.

Although Microsoft does not provide an universal “one disc rules them all” Windows 7 installation media, however the function is indeed supported. User just need to delete and remove the ei.cfg from any Windows 7 ISO disc image to convert the image into universal disc of any edition Windows 7 installer.

For user who has the ISO image of Windows 7, and wish to make it an universal installer for any and all supported editions of Windows 7, as shown in illustration below, now has an easier way to modify the ISO. Instead of manually unpacking and extracting the content of ISO image (or copying files from DVD) to HDD, deleting the ei.cfg and then repacking or rebuilding installation files back into ISO to burn, user can now eliminate troublesome procedures by making use of “ei.cfg Removal Utility”.

Windows 7 Universal Disc Image to Install All Editions

The ei.cfg Removal Utility is a simple tool that will disable the ei.cfg from any Windows 7 ISO disc image, thereby converting the image into a “universal disc” that will prompt the user to select a preferred edition during setup. ei.cfg Removal Utility works directly to patch the ISO image, by toggling the deletion bit in the UDF file table to instruct the operating system to ignore and remove ei.cfg, or treat it as if it does not exist. Best of all, ei.cfg Removal Utility can reverse the patching to restore the ISO disc image to its original state when the tool is been used to apply on a disc image that previously been patched by the utility.

ei.cfg Removal Utility is a standalone portable app, and thus no installation required. In fact, the program does not have much user interface. After selecting the target Windows 7 ISO, the disc image will be patched right away. So make sure a copy of ISO backup is done.

    As of Dec 2012, this utility does not work with the Windows 7 USB/DVD Download tool, it detects the change made to the .iso and says it’s not a valid .iso. If I run the utility again to restore the file, the utility says nothing.

    • Seerak

      Ignore the foregoing: it’s Daemon Tools creating bad .iso’s. Never mind.

    • josh

      hi do not modify the iso, just use Windows 7 USB/DVD Download tool to transfer the iso to usb then delete the ei.cfg inside the usb

  • Rajiv

    I have downloaded “Windows 7 Ultimate SP1-U ISO English x64: X17-59465.iso” and to create an all-edition Windows 7 ISO image used “ei.cfg Removal Utility”. Thereafter, copied Windows 7 installation on Pen Drive by using “Windows 7 USB DVD Download Tool”. Nevertheless, I have not found any operating system selection menu during installation.

        I can’t stand people like you. Why did you bother posting?

    OH MY GOD I FREAKING LOVE WHOEVER MADE THIS

    You have NO idea how many times I’ve tried to get rid of this ei.cfg file, only to result in the Windows 7 Installation error saying something about Install.WIM file missing.

    This tool was extremely easy to use. Many thanks!

    By the way, I used this on a Windows 7 Home Premium 64-Bit disk downloaded from this very website.

  • LazyD

    I have done this in the past and it worked fine, however…

    I downloaded a new legit image from MS about a week or so ago (Sept 2011), removed the ei.cfg file from the image (with poweriso, same as I did the time before), burned the disc and booted it, no choice of version screen! Just went straight into the Professional version install.

    Have MS changed something recently? I know I did it right because I checked the iso that I modified again, and unlike the original, it doesn’t have ei.cfg. I also created it again, removing the ei.cfg again and mounted that image to a vm and again it did not ask me which version I should install.

    Anyone know what’s going on?

    My question is: After the file is patched, is the SHA1 result supposed to match the original checksum for the file? (because mine certainly does not) However, the copy I made of the iso does!

    I have win 7 ultimate with sp1 x64 iso

    Will it be possible to install win 7 ultimate with sp1 x86 from this iso if i remove/disable ei.cfg ?

    • nimd4

      Supposedly it's not possible to downgrade a 64 bit installation to 32 bit, but also if you have more than 3GB of RAM – you wouldn't want to, right? Here's what I looked @ google.com/search?q=downgrade+windows+x64+to+x86 🙂

  • Asker

    Sir, I only have one question:

    You posted a screenshot and how is it possible to take a screenshot while installing windows?

    Please let me know, I am very curious……

    As a Microsoft Registered Partner I do not recommend using a Keygen. Go out and buy a license! Very good little tutorial.

      It's not gonna happen, pal. I've disabled the defragmenter, scheduled tasks, start and indexing programs and/or services; yet, when the computer is idle – the HDDs start shuffling (when I explicitly do not want any HDD activity). This is just one example of what can be SEEN: Windows doing what I do not want it to do. Just imagine the other million-and-one things that the OS is doing behind our backs. So, I'm not paying for it – it's simply a defective product: as Windows has always been. Not trolling here, I'm open for discussion; but Microsoft programmers can't give straight answers to these kinds of questions – because they know what they're doing. =)

      • shawn

        you got that right. They keep people interested by putting out new products, yet they all contain the same crap they can’t fix from the previous one. then they discontinue support and that is their excuse we don’t support thatr anymore.

        • Frank Erureye

          Of course what has been improved in Windows 7 is the ability to return to your original os [the key thats on the sticker ,on the pc , laptop.] If you pc didn’t come with an dvd install now you can easily download the iso.

      • Denise

        Whether you like Windows or not, and whether you think it’s worth the money or not, you cannot use the software for free. It is not open source and it is protected by copyright. If you want something for free you will just have to abandon Windows.

    I have used this method to make universal disks from an ISO of both 32 (file X15-65732) and 64 (file X15-65733) bit version of Windows 7 Home Premium. They both work fine. If the download is corrupted (interrupted in any way) you will have errors in the ISO.

    Try and use a download utility to prevent the situation.

    Cheers.

  • John

    I have download the file X15-65804.iso and remove the ei.cfg from ISO and burn the ISO in DVD but the installer fail and giving me an error that ntkernalpl.exe is not found or corrupt. Give me solution if anybody have for this problem.

  • Alex

    Is it possible to make a universal dvd including both architechture? x86 and x64

    • Jack

      Sort of. You could possibly dual boot the disk or drive but you'd need a drive with about 8GB.

      • Anthony

        Well, that is possible with a dual-layer disc. That said, if you have the disc, how would you do it?

  • pakdoeo

    yes u can use windows 7 for free… ;D

    • Denise

      Not legally.

    To mwhitt:

    Gosh, do you still think you can use Windows 7 for free? Grow up, man!

  • mwhitt

    This works great!! My only problem is that after installing I am told to present the "key" withen 30 days. How to go about that? Should I just use a key

    generator?

    Thanx!!

    • un-nonamous

      dont be dumb……you need to have a license sticker or your own key
